Patent number: 6161313Abstract: A metatarsal guard for footwear comprises an arched body which covers a dorsal surface of a wearer's metatarsal foot area. The arched body has lateral bottom edges for engaging a footwear sole to transmit loads from the arched body to the footwear sole. Slits are defined in a rear portion of the arched body so as to form a longitudinally extending central T-shaped tongue and two longitudinally extending lateral tongues in order to increase the flexibility of the metatarsal guard. The T-shaped tongue has a rear edge extending in a concave curved line transversally of the footwear so as to prevent transmission of punctual loads to the wearer's foot. By optimizing the number and the configuration of the tongues, both the wearer's comfort and protection are maximized.Type: GrantFiled: January 26, 1999Date of Patent: December 19, 2000Assignee: STC Footwear Inc.Inventor: Michel Bisson

Patent number: 4575953Abstract: A safety shoe having a toe protecting cap which is shaped to conform substantially to the tip of the shoe and is provided at its portion facing the sole of the shoe with an inwardly directed flanged rim. This toe protecting cap flanged rim is inserted into a groove provided in the vertical end face of the one piece sole and is retained therein by attachment of the upper of the shoe, whereby the upper groove wall is set back with respect to the lower groove wall by at least the thickness of the toe protecting cap. The shoe upper is attached to the lower groove wall. The manufacture of the safety shoe is simplified and production cost savings are realized by providing a one piece sole having a groove therein, whereby at least one of the height and depth of the groove is slightly less than the corresponding thickness and length of the flanged rim of the toe protecting cap.Type: GrantFiled: March 12, 1984Date of Patent: March 18, 1986Inventor: Gerhard Hetzel

Patent number: 4566197Abstract: A shoe of the moccasin type is made crush- and deformation-resistant toe by use of a premolded box toe stiffener for stiffening the toe region of the shoe upper. The stiffener is of flexible, resiliently stable character, characteristically remaining in or reverting to its original configuration, including an upstanding flange of curved configuration for lying against and providing securement to the corresponding interior surface of the upper. Principal and side tabs extend rearwardly from the bottom edge of the flange for securement to the sole part of the upper, or to an insole. Exterior foot-opposed surfaces of the stiffener are coated with heat-activated adhesive for adhesive securement to said shoe interior surfaces. The flange has a rear, foot-side inner surface devoid of adhesive, being exposed within the shoe. The method of making the shoe involves thermally forming the stiffener by molding from a blank of heat-formable material.Type: GrantFiled: August 1, 1983Date of Patent: January 28, 1986Assignee: Interco IncorporatedInventor: Fred B.

Patent number: 4412393Abstract: A ballet dancer's toe dancing ballet shoe is designed and manufactured more simply than conventional ballet toe shoes. A sole supporting shank of the toe shoe has a tip flap at the front thereof which may be folded up to define the front panel of the completed ballet toe shoe. The shank is applied to a male mold member which is inserted into a female mold member cavity and resin is inserted into the space between the mold members for defining a toe box support frame in which the inserted portion of the shank and tip flap are embedded. The shank is comprised of a leather-like material. The completed combination of the shank and toe box support frame are removed from the mold members. A ballet toe shoe upper is fastened to the shank and over the exterior and in the interior, as well, of the toe box support frame.Type: GrantFiled: July 10, 1981Date of Patent: November 1, 1983Assignee: Ballet Makers, Inc.Inventors: Nicholas Terlizzi, Jr., Donald Terlizzi

Patent number: 4398358Abstract: An athletic shoe is disclosed which is primarily adapted for use in rapid start-stop sports, such as tennis, racquetball, handball and the like. The athletic shoe includes a sole, an upper secured to the sole and a toe cap which is secured to the sole and the upper. The toe cap defines a plurality of narrow slits which extend generally longitudinally of the sole. The narrow slits increase the flexibility of the toe cap and provide room for the toes of the user during rapid stops primarily to prevent bruising of the big toe.Type: GrantFiled: March 12, 1981Date of Patent: August 16, 1983Assignee: Return on Investment CorporationInventor: Carl W.
